Table 2. Correlation Between CT-ADP or PC and Bleeding Scores.

Bleeding Score^a	Fraction With Maximum CT-ADP, No./Total No. (%)	Median (Range)
Bleeding Score^a	Fraction With Maximum CT-ADP, No./Total No. (%)	CT-ADP, s	PC, 10³/μL
0-1	18/65 (28)	155 (70-300)	67 (13-98)
2	11/26 (42)	271 (69-300)	56 (16-95)
3-4	7/8 (88)	300 (183-300)	56 (25-93)
P value	.003^b	.006^c	.15^c

Abbreviations: CT-ADP, closure time-adenosine diphosphate; PC, platelet count.

SI conversion factor: To convert PC to ×10⁹/L, multiply by 1.

^{^a}

Score ranges from 0 (no bleeding) to 4 (major bleeding).

^{^b}

Fisher exact test.

^{^c}

Kruskal-Wallis test.
